Recover from a PC Coma
Occasionally, a PC may go to sleep and not wake up. It gets stuck. Troubleshooting this issue is pretty simple. The problem isn’t as common as it once was, but the solution is the same. First, turn off the computer. Then, update the power management software.
To turn the power button into a true Off switch, press and hold the Power button for five to eight seconds. After that length of time, the computer will turn itself off.
Yes, it’s okay to forcibly turn off a computer when it’s in a coma.
When you turn on the computer again, your next task is to update the PC’s power management driver software. To complete that task, you can phone your dealer for more information, but you’ll probably be directed to the manufacturer’s website. After you’re there, look for the Support or Download Drivers link. Find the latest power management driver software for your PC and update it.
You can also use the Windows Update service to ensure that your computer has the latest power management software.
If the problem persists, don’t use Sleep mode for your PC. Instead, consider simply turning off the monitor when not using that computer.
Using the Power button to forcibly turn off a computer is a desperate measure. Do not use the press-and-hold method as your normal way to turn off the computer. Try to troubleshoot shutdown issues, not ignore them.
